Cub Cadet 2166 manual Servicing the Paper Element, Cleaning Engine, Spark Plug

Servicing the Paper Element

Every 100 hours of operation (more often under extremely dusty or dirty conditions), inspect the paper element. Replace the element as necessary.

1.Unfasten the air cleaner cover retaining knob and remove the air cleaner cover (See Figure 24).

2.Remove the foam precleaner by sliding it up off the paper element (See Figure 24).

CAUTION

The air cleaner element cover plate (See Figure

24)must be properly installed to seal against the gasket surface of the paper element.

3.Remove the wing nut and element cover plate, then lift out the paper air filter element.

4.Do not wash the paper element or use pressurized air, as this will damage the element. Replace a dirty, bent or damaged element. Handle new elements carefully; do not use if the sealing surfaces are bent or damaged.

5.When servicing the air cleaner, check the air cleaner base. Make sure it is secured and not bent or damaged. Also check the element cover for damage or improper fit. Replace all damaged air cleaner components.

6.Inspect the rubber grommet seal (See Figure 24) for deterioration, cracks, and for a snug fit on the carriage bolt. Replace if damaged or worn.

7.After making certain the carriage bolt is secured in position by the retaining ring, slide the grommet seal fully onto carriage bolt. See Figure 24.

8.Install the cover plate on the carriage bolt and secure with the wing nut. Do not overtighten the wing nut, which could deform the cover plate.

9.Reinstall the air cleaner cover. Make certain the cover retaining knob is tightened securely.

Properly cleaned and installed air cleaner elements significantly contribute to prolonging engine life.

CLEANING ENGINE

This tractor has an air-cooled engine. Air must be able to circulate freely around the engine through the flywheel screen, through the cooling shrouds and over the fins of the cylinder head and cylinder block. Keep these areas free of accumulated dirt and debris or the engine will overheat; possibly causing extensive engine damage. Regularly clean the inside of the side panels, dash intake screen and grille to ensure adequate cooling. If debris has accumulated inside the cooling shrouds of the engine, the blower housing and cooling shrouds should be removed and the cooling fins cleaned.

NOTE

This machine is designed to cool properly with the side panels in place. Operating without the panels could cause premature accumulation of dirt and debris on the engine, resulting in inadequate cooling.

SPARK PLUG

WARNING

To avoid possible injury, be sure the engine is off and has cooled before making any adjustments or repairs.

NOTE

Remove all dirt from around the spark plug before removing.

To remove the spark plugs, always use a spark plug wrench. Check the gap after every 100 hours of operation.
